kaloilla

Kaloilla is a Finnish word, the adessive plural form of the noun kala ("fish"). As an adessive case form it typically expresses location ("on" or "at") or a possessive relationship equivalent to English "have" when used with the verb olla ("to be"). Morphologically, it combines the plural stem of kala with the adessive suffix -lla/-llä and follows Finnish vowel harmony and consonant gradation rules.

In usage, kaloilla can indicate physical location — for example, in a context meaning "on the fishes" — or denote that the fishes possess something when paired with olla: Kaloilla on omat tavat ("The fishes have their own ways"). The adessive plural is one of several locative and case forms in Finnish and contrasts with forms such as the nominative plural kalat, the partitive plural kaloja, and the inessive kaloissa ("in the fishes").

The form appears in everyday speech, literature, and ecological or culinary contexts where plural, locational, or possessive relationships involving fish are described. As a grammatical form rather than a lexical item, its meaning depends on syntactic context, and it functions according to standard Finnish case and agreement patterns.
